Kitchen sink upgrade

One of many projects going on right now on our 2018 Tab 400. Inspired by another Tab 400 owner's project that they documented. I used the same sink (but from a different brand name): https://www.amazon.com/dp/B002CZPTSE ... it's basically the largest sink you can put in a 400 without having to cut the supports under the cabinet, but it takes some careful positioning to get it in without running into those supports.

The faucet needed its own hole, and some other minor plumbing adjustments:

The sink is larger, which required some saber-sawing to enlarge the hole, but with a few hours of careful repeated measuring, it came out well.

The sink has an option for a wooden cover, which another Tab owner had planed down to make it closer to level with the counter top (I have a planer, but we haven't decided whether we'll do that or not).

To simplify the plumbing and free up space under the sink, I installed a "waterless trap" i.e. a "not-a-J-trap" trap: https://www.amazon.com/dp/B085MMJJ49 ... with the deeper larger sink I had to move the plumbing around a bit anyhow, so this wasn't a big deal to change.

That's actually as far as I've gotten. The sink will get properly installed probably tomorrow, now that everything is prepared. I had to lower the T for the drain by 1/2", and cut a new straight piece (what was left of the original was 1" too short). Note the adapters from the 1/2" to the smaller metal fittings that came with the faucet; there are lots of different thread standards, and the correct step-down adapters are here: https://www.amazon.com/dp/B0DKFYDR1R

This project has taken far longer than I planned for, but mainly because each step needed a few parts that I didn't have, and most were difficult to find locally. It's a bit scary to use a saber saw on a counter (not to mention the oscillating multi tool on the PVC plumbing), knowing how easy it is to mess something up, but thankfully thus far I haven't done anything so boneheaded that it can't be easily hidden e.g. by the lip of the sink. But as always, the rule of thumb is measure twice, and then don't cut until you remeasure a few more times and think things through again.
